Slavery is a complex human phenomenon. Historically, slavery was an overt process whereby one human being openly ‘belonged’ to another person or to another civilisation, generally for the purposes of labour, debt repayment, or in the context of prisoners of war. Modern slavery includes human trafficking as well as servitude, deceptive recruitment, forced labour and debt bondage. In most cases it operates illegally and covertly.
The United Nations estimates that there are 25 million victims of forced labour being exploited in global supply chains across the world today. Industries most commonly affected include agriculture, manufacturing and construction.
